Abstract
This invention relates to a matrix of a solid electrolyte having a microstructure in which a non-reactive polyalkylene glycol is held on a co-crosslinked product produced by chemically co-crosslinking a hyperbranched polymer with a crosslinkable ethylene oxide multicomponent copolymer, such that a lithium salt is dissolved in the matrix. A negative electrode active material layer is a layer obtained by dispersing a negative electrode active material and a conduction aid in a lithium-ion conducting solid electrolyte. A positive electrode active material layer is a layer obtained by dispersing a positive electrode active material and a conduction aid in a lithium-ion conducting solid electrolyte.
